The appeal of advertising to buying motives can have both negative and positive effects.
Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people’s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money.
Sometimes advertising is intentionally misleading. A few years ago a brand of bread was offered to turned out that the bread was not dietetic (适合节食的), but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf.
On the positive side, emotional appeals may respond to a consumer’s real concerns. Consider fire insurance. Fire insurance maybe sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance.
A. stressing their high quality
B. convincing him of their low price
C. maintaining a balance between quality and price
D. appealing to his buying motives
